GM 10 bolt questions

Just a few questions.

What is the fluid capacity for a 10 bolt GM?

I saw this on one of the hot rod shows on a Sunday morning. Has anyone ever put the rearend grease, posi lube in a zip lock bag and placed it in the housing and bolt up the rearend cover? If it works that would sure make for a clean fill. They said the plastic just melted away and blended into the oil. Plastic is a petrolium base. Lets hear good or bad. Thanks Keith

 

really?
Sounds like a bad idea. kidding?

 

5-6 pints. I wouldn't want anything extra in there.

 

Whats wrong with pulling the plug and just filling it there? As far as capacity, it normally take a little more than a quart or so. I fill them and use an allen wrench to check the level..Put the short end in the hole and when it's about 1/8" to half way up, your done.
I personally would not do the bag trick..petroleum based or not..

 

I would be worried about the bag wrapping around a bearing and starving it of oil. Besides, it ain't that hard to fill a 10 bolt the conventional way.

 

I wouldn't do the plastic bag thing either.......

 

I would not do the bag thing but sounds like a mail-order outfit or a shop that sells completely ***embled rear ends trying to eliminate the possiblility of a customer not putting grease in his newly purchased rear end ***embly. LOL

 

I wouldn't use the bag trick. Just fill her through the plug

 

We have a machine at my work that forms pockets in a plastic film then puts a layer of plastic film over the top and seals it all around.. Sort of like pre packaged lunch meat.You should see what the t*******s can do to the drive shafts and bearings.. No way.

 

Looks like everyone agrees, NO Plastic bag.

I have just 1 more question. Do you still need the posi addative if your using synthetic gear lube?

 

Yes on posi lube, as it is a friction modifer for the clutchs, the cone type posi I don't know ?!?!........and I was told by a oil rep that normal oils are microscopicly like gravel and synthetics are like ball bearings in laymens terms.

 

Ain't that why they invented the mustard bottle?

 

grab the gear lube that has the pointed top....just squirt the **** in

 

that sounds like a real good way to **** up a perfectly good rear end.

 

Just a heads up, your posi will WORK BETTER and LAST LONGER without the additive.

The additive is made to MAKE your posi slip... bad for performance, but the customers don't bring their cars in all the time complaining about chatter around corners.

 

I have heard arguments for and against it...it is also supposed to have a conditioning agent in it that makes the clutches last longer.

whatever it is, I just want to know why it smells like a salmon fillet left on Your back porch for a couple days.

 

I'm sure the reason for the bag trick is on a lot of newer 10 bolts there is NO fill hole,

that being said, I still wouldnt use that on my 81 camino daily

 

I saw them do the baggy trick on junk yard wars a few years back but they only needed the rear end to last a very short time.

And if the capacity question did not get answered, I just did mine and it took 3 of them squirty bottle quarts to fill it perfectly.

 

What kind of 10 bolt rears have no fill hole?

 

Do you really believe everything you see on TV ? I wouldn't trust the stupid ideas they come up with sometimes on the Spike channel ! Do it the way everyone has done it for many years , just take the plug out and fill till it comes out then plug the hole back up . Now that wasn't so hard was it ?

 

ive used the baggy trick in my 4wd for on the trail fixes but changed it and flushed housing when i got home

 

No bag, bad idea.

 

The way it is now I am getting a lot of popping and chatter when I go around corners and when I back up. I am popping the cover off this weekend and cleaning the rearend out with brake cleaner and adding synthetic lube along with posi additive. (without the plastic bag)

 

80's g-bodies i know, may be others

 

Not buying no fill hole.

How do they get gear oil in a c-clip type axle?

Fill hole is in the front casting on every one I've looked at.

 

you must never of had a posi that didn't slip and acted like a spool . not a happy sound or feeling, use the lube.

 

X2.
10 bolts take usually 1.8 to 2.3 qts of lube. Fill it until lube starts to trickle out of fill hole. Done. Never heard the bag idea. But....if it was on TV it has to be true, right?

 

I have an '80s Grand National rear end that took a little less than 2 quarts of oil. It has the fill plug and the stock cover, but I did see that plastic bag thing done on TV once a few years ago. I think it was on Trucks during a budget build as a trail trick.

 

I have the solution for no fill hole...Make one
I had an 85 chevy with the 14 bolt that did have a fill hole. We tried and tried to get that plug unscrewed but it just stripped out. not even heat or impact would budge it.
I knew it was low on fluid. I had to run the truck from Omaha to Denver and had to leave the next day...what to do???
Y'all know those little rubber vacuum line caps in the "HELP" isle of the autoparts store?
I drilled a fill hole at the oil level line a little smaller than the 1/4" rubber cap.
I filled the axle with lube.
I put a small punch into the rubber cap and pushed it round end first halfway into the hole...same way you install rubber mutes on a commercial buildings steel door frame
It never leaked.
